Rockland Bleuprint Kit Cyanotype


Blueprints are rich blue images of photographs or drawings. A transparency or drawing on clear plastic is laid over paper or cloth coated with blueprint solution. Sunlight (or a halogen bulb) exposes it, and running water is all that’s needed to make it permanent. Makes 24 8×10 prints

The chemicals used to make them, potassium ferricyanide and ferric ammonium citrate, are also the basis of the artist’s colour Prussian blue.
